To all whom t may concern.'

Be it known that l, HERBERT fto'ri-iwiiiii, a citizen of the United States, residing at Scobey, in the county of Sheridan and State of Montana, have invented certain new and useful lmprovements in Sheet-Guides for Cylinder-Presses, of which the following is a specification, reference being had to the accompanying drawings.

rlhis invention relates to sheet guides for presses, and particularly to guides for feed ing sheets in cylinder presses.

'llhe general object of this invention is to provide improved means for guiding the sheets for cylinder presses, andparticularly to provide adjustablemeans for this purpose coacting with a graduated rule, whereby the adjustment of the guide may be quickly and readily secured.

A. further object 0f the invention is to .provide a device of this kind wherein the sheet guiding member proper may be shifted from a lefthand to a rigl'ithand position.

A further object is to provide a device of this character in which the sheet guiding member may be readily released from its engagement with the feed board or readily engaged therewith.

Still another object is to provide a sheet guiding member having sheet engaging fenders which are adapted to be turned down into or out of operative position and enables one to feed paper which has been wrinkled or curled.

Another object in this connection is to form these fingers or fenders of hard rubber composition, to thereby eliminate the genera` tion of electricity as where metallic fenders or fingers are used.

A. further object is to so construct the sheet engaging or guiding member proper Y that the sheet will not slip under the guiding member when being fed.

Still another object is to provide a feed f board having a transversely extending slot with a transversely extending metallic strip bent to provide substantially a dove-tailed channel, this strip being inserted in the groove of the feed board, the flat margins of the strip being provided one with a scale for setting the guide member at the lefthand end of the feed board and the other margin with a scale for setting the guide member at the righthand end of the feed board.

to provide a rod or slide shiftable through the dove-tailed channel, this rod having an indicating member at one end coacting with the scales above referred to, there being a. sheet engaging guide member which may be engaged with said rod, either at one end or the other end of the rod, to thus provide for vguiding the paper either by its righthand edge or its lefthand edge` Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan of a feed board provided with my improved paper guiding attachment 5 Fig. 2 is a longitudinal fragmentary sec-V tional view through the board and channel and the latch end of the paper guiding rod;

Fig. 3 is a section on the line 3 3 of lfig.` 1;

Fig. 4L is a fragmentary vertical sectional view through the channel, a portion of the feed rod and the paper guiding block; j

Fig. 5 is a transverse section on the line 5-5 of Fig. l;

lfig. 6 is a perspective view of the paper guiding block; and

Fig. 7 is a fragmentary perspective view of a portion of the rod 17 and the head 19.

Referring to these drawings, 10 designates the feed board of a cylinder press, 11 designating the feed edge of the board, that is, the edge which is adjacent the cylinder. rlhe feed board is longitudinally grooved as at 12 for its entire extent, this groove, as illustrated, being rectangular in cross section and the face of the feed board, on each side cf the groove, is chamfered as at 13. Disposed within this groove is a strip of metal, designated generally 111, which, as illustrated in Fig. 8, is bent to provide a longitudinally Y extending channel 15 having laterally extending wings cr margins 16, these wings or margins being received within the chainfers 13. The channel 15 has its walls ein tending downwardly and laterally from the junction `of the channel with the wings and then extending downward and centrally, and

then parallel to the bottom of the grobve 12. ln other words, the sides of the channel are formed withV overhanging walls.

lhe wings 16 are graduated to provide two scales designated and B. rlFhe gradu- And a further object in this connection ations on scales are preferably lil/'t2 gf il fromtheniiddle offthe'channeledstrip 14.

an inch apart, and each scale-is divided intov 6 lengths, designated by the numerals 1, 2,

toward one end thereof7 vthe remainder ot' the strip not being provided'with indicating characters or graduations. lIfhe middle of the" stripis indicated by the letter X in the drawing and this point is disposed exactly on aline with the middle of thefeedv board. T he stripis held to the feed board by means of'v screws or any other suitable devices of this character and the top ofthe strip is, of course, flush with the upper face ofthe feed board. Y Y

Slidably disposed within the strip is an elongated slide,. designated 17, having the fornrof a rod, whose width for the greater portion of' its length is slightly less than the, mouth of the channeled strip 14C, but whose ends arev wider and tit within thc channeledY strip, these'end portions 18 and 19, which. I willhereafter term heads, being approximately hexagonaly in cross section so as to, tit the channeledrstrip and extend. beneath the overhanging side walls thereof so that they will have interlocking sliding engagement with the strip, the slide or. sliding rod 17 having its upper. face Hush with the upper face ofthe channel strip 14. At one end of the slide 17 there is d-isposed a latch device to hold the slide in` adjusted position within the channel and as illustrated', this latch device comprises a strip of resilient metal, designated. 20, this strip beingy riveted at one end to the rod 17 inward ofthe head 18 and extending beneath this head and then extending upward as at 20a and angularly bent to form a thumb ypiece 21 whereby the spring may be raised.

The heads 18 and 19 are both somewhat shallower than the channel 15 but the spring 20' rests upon the botto-ni of the channel and urges the head 18 upagainst the overhanging walls of the channel so as to bind the vhead 18 and therefore the rod 17 in place andY thus hold the slide or rod 17 in its adjusted positions. release the slide so as to permit it to be shiftedI along the channel, the spring- 20 is raised by thethumb piece 21 and this permits of'this shifting movement. The head 18 and the head' 19 are bothprovided with a pair of vertically extending perforations 0r sockets, 22, as illustrated best in Fig. 2.

CoactingV with the heads 18 and 19 is a guideblock Q3 which forms the paper guiding member. This guide block has on its under face the downwardly projecting pins or studs 2,4 which ,may be disposed in the sockets 22 of either head. It is to bel noted Then it 'is desired to that one of these pins 2st is tlush with the inside face 25 of the guide block. The guide block is provided upon its upper face with apair of. earsQG and pivotally supported between these ears is an arm 2T having a cross head 28 at its outer end. The cxtrcniities of this cross head ar slotted and disposedr in these slots are the curved hngers or fenders 29 which. are preferably lnadc ol' hard rubber composition and have a certain degree of resilience. Then the arin 51T is turned into a position approximately parallel to the upper face of the guide hlm-lt 2). these fingers 29 extend downward laterali)v on each side of the guide block, as illustrated in Fig. 1, so as to engage a sheet o' paper and hold it down upon the vl'eed board. For the purpose of adjusting the pressure exerted by these fingers 9.9, l provide an adjusting screw 30 which passes through the arm 27 and engages the upper face of the guide block. rllhus the degree of pressure exerted by these lingers can he readily controlled.

In the practical use of this invention. the sheet guide is adjusted by shifting the slide 17 along the channel 15 using the inner end face of the head 18 as thc index to coact with the scales Ai or B. When this index mark 31 is where it should he for the length of the sheet intended to he fed. the spring 20 is released and securely locks the slide rod from any movement duc to thc jar or vibration of the press. if it he desired to use a left hand guide. as for instance on a work and turn run, it is only necessary to place the guide hlock on the head t8 with the face 25 of the guide block facing toward the right-hand end of the feed table. The scale B is for a righthand feed and the scale A for a lcfthand feed. if it is desired to feed a sheet one foot longl` on a work and turn joh7 the indicator would he set for the right-hand guide in Fig. 1 using the scale B and for feeding the other side of the saine sheet, the lefthand guide would he used and the guide block would he disposed on the` head 18. its I stated before. each scale A. and B is divided into (3 lengths but this indicates 6 on each side of the center or middle X so that the length indicated on the scale is doubled and thus while the numeral 1, for instance. of the seal(` A is hut 6 from the .middle X, yet when tlu` indi eating line disposed at this numeral l on the scale A. it is sct for a. one foot sheet, It will be seen. therefore, that theI `guide block may be disposed either ai the righthand side or at the lefthand side and that it is just as easy to set the device for the.` righthand guide as for the lefthand guide. the only diderence being tha t different scales are used.

Itis to be understood that the operativi` feeding the pressl stands at the end marked lun llO

Leraar/e l" i Y in Fig. 1 and that the sheets to be printed are fed against the member 23 at the opposite end of the feed board marked Z, that is, if the operative is using a righthand feed. The indicator in Fig. 1 is set to properly guide a sheet two feet long and if it vas a work and turn job, that is, a job where one side of the sheet is printed and then the sheet turned over and the other side printed, all that would be iiecessary to do in order to feed the sheet With its other side turned up and to a lefthand feed would be to lift olf the O'uide block 23 from its positionon the bar l? illustrated in Fig. fl, and replace it with its tivo pins in the openings 22 of the head 18. This would then set the guide block for a lefthand feed for this saine sheet, thatis, a feed against a guide which is disposed at the lefthand of the sheet. The reason for using tivo scales is because it is confusing to use even a co1nnien foot rule scale backward, and in order to avoid this confusion and thereby gain time and secure accurac 1 the scale B is used for a righthand feed andthe scale A is userl for a lefthand feed. As the operative stands at the end marked Y he is able to readily read either one of the scales and set the guide either Way by reference to the proper scales. For instance, if it be desired to feed a sheet one foot long, the indicating mark 31 Twould be disposed on the numeral l of scale l and this would bring the guide block 23 within one foot of the middle pointl of the table and 1f it were desired to use a lefthand feed for the same sheet, the indicating mark 3l would be set in ahnement With the numeral l of the scale A and the guide block 23 Would be lifted outand placed upon the head 18 giving eXactly the same feed and distance on the lefthand side as vWas before had on the righthand side, Without in any Way confusing the press feeder.

One of the minor advantages of my constructionresides in the use of the fenders or `fingers 29 Whichcnables one to feed paper that has been wrinkled or curled these fenders bringing just 4enough pressure on the paper up to 24 can be guided. lt is ob-` vious, however, that the guide may be made longer or shorter than this, depending upon the size of the press and to accommodate sheets of paper of various sizes.
